Flame Retardants & Smoke Suppressants

Chemical and mineral flame retardants belong to a diverse family of naturally occurring and man-made chemical compounds. These retardants reduce the flammability of polymer formulations. Fire can occur in many different situations and across innumerable applications. As such, flame retardants can be found in everything from electronic devices to household furnishings.

Flame retardant additives are commonly used in the thermoplastic, thermosets, textiles and coatings industries. The right flame retardant additive for your application depends on several factors:

  • The polymer being used
  • Compounding process conditions
  • Temperatures
  • Service requirements for the finished part

The Advantages of Flame Retardants

Flame retardants are organized by different classes depending on their chemistry, particle size, composition and applications. Generally, they can be separated into mineral, organohalogen compound and organophosphorus compound categories.

Flame retardants offer a powerful advantage for many industrial applications, but they should be selected with the utmost care and safety.
